lazy-learn is a high-level Python interface for automated machine learning (AutoML). While there are many AutoML libraries available each typically solves a niche area of the overall ML pipeline without providing a covering and approachable end-to-end system.

The aim of lazy-learn is exactly to address those shortcomings. Given a dataset, lazy-learn will analyse types and distributions of attributes, preprocess, feature-engineer and ultimately train models to be used for further evaluation or inference.

Current stable version is 0.0.3. The upcoming updates will support:

• Abstract construction of model architectures
• XGBoost, LightGBM, Adaboost and Catboost architectures
• Time partitioning of datasets (Added in 0.0.4)
• Automated Hyperparameter Optimisation (HPO) (Added in 0.0.4)
• Text features
• An interface to AutoGluon
• Outlier detection and handling
• Automated suggestions of performance metrics

Using lazy-learn revolves around the LazyLearner class. You can think of it as a kind of project, and it is the wrapper for any experiment within lazy-learn. You can consider a simple example with the California Housing dataset:

from lazylearn import LazyLearner
from sklearn.datasets import fetch_california_housing
# get some data
data = fetch_california_housing(as_frame=True)
df = data["data"]
df["MedHouseVal"] = data["target"]
# instantiate and run the LazyLearner
learner = LazyLearner()
learner.create_project(data=df, target="MedHouseVal")
learner.run_autopilot()
# evaluate results
print(learner.leaderboard())

lazy-learn requires:

• pandas
• scikit-learn
• xgboost

pip install lazy-learn
